Description

I received a private report that -print-file-name=libc++.modules.json doesn't work well in mac m1. Maybe this is related to the installation path of libc++ in MacOS.

Verify needed.

Contributor guide

Research direction
Investigate the installation path of libc++ modules on macOS M1. Check the CMake configuration and the expected location of libc++.modules.json. Verify if the path is correct on Apple Silicon.
